13 Claims.

My invention relates to new and useful improvements in attachments forsewing machines, and more particularly to an attachment that will foldback the marginal edges of the fabric adjacent the line of stitching andpress these sofolded edges in a neat and workmanship-like manner. l

rlhe invention in its broadest aspects is similar to the joint inventionof Tom Anderson, Hugh Grifih, and C. M. Henson, filed on December 11,1934, Serial Number 756,998, for Folding and pressing attachment forsewing machines, and allowed January 6, 1936 resulting in Patent Number2,055,470 issued on September 29, 1936.

In that application, there was provided a swinging frame mounted on thebed of the sewing machine, in which frame there were horizontallymounted an over-running clutch and a heated roll which cooperated withan idle roll also mounted on the swinging frame, the driving mechanismbeing connected through the frame and to the over-running clutch andpresser roll.

The present invention contemplates a greatly simpli-led structure, asthe horizontal frame on the bed plate has been dispensed with, as wellas the horizontal shaft which supported the overrunning clutch andpresser roll.

Many other distinguishing features are present, which will be noticed asthe specification proceeds.

One of the main objects of the present invention is to provide a simpleand elcient means of turning back the marginal edges of the clothadjacent the line of stitching, one of the marginal edges being turnedupwardly before it reaches the needle and the other marginal edge beingturned downwardly just after it passes the needle, so that by the timethe fabric and its marginal edges have reached the presser rolls, theyextend in the desired opposite directions to then oe properly pressed.

A further object of the invention is to provide a small auxiliary tablethat is mounted on the bed of the machine adjacent the needle. Thisauxiliary table being sightly raised from the main table permits thefabric to be fed to the needle and, at the same time, allows for theVvide this auxiliary bed plate together with its associated parts so thatone layer of the cloth, when it passes under the presser foot, will haveits margin turned in an upward direction and will be held in thisposition until it strikes the presser rolls, whereas the under layer ofcloth will remain in its flat or horizontal position until it reaches apoint just beyond the needle, where it will be deiiected and turneddownwardly to a vertical position, so that as both marginal edges reachlthe rolls, they will be in position to be properly pressed.

Still another object of the invention is to provide an attachment forpressing the Vmarginal edges of the seamed fabric back on the fabric tothus do away with the hand ironing or pressing that is generally aseparate operation.

Still another object of the invention isto provide an attachmentthat maybe readily fitted to a conventional type of sewing machine, itnecessitating a changing of but relativelyv few parts and the additionof others that may be quickly performed by any mechanic skilled in theart.

Still another object of the invention is 'to provide an attachment thatwill position the marginal edges adjacent the seams, so that they may beproperly folded and positioned just prior to the pressing action.

Still another object of the invention is to provide a worm and pinionarrangement for driv- .ing the presser roll that is synchronized withthe feeding dog mechanism ofthe sewing machine, so that the attachmentwill also assist in the feeding of the fabric to and away from theneedle. ,c

Still another object of the invention is to pro'- vide an attachmentwherein there are butv relatively. fewparts above the table of themachine and these few parts arranged adjacent the presser foot andneedle.

Still another object of the invention is to provide a simplified presserattachment wherein the presser roll is set in a vertical position andoperated directly from the main shaft of the sewing machine.V

Still another object of the invention isto provide a pressing attachmentthat may Yloe relatively quickly and easily applied to the conventionaltype of sewing machine, and wherein if it is desirable to omit thepressing on certain forms of goodsthe only change necessary will be toloosen the set-screw in the roll and remove the roll and use the machinein the ordinary manner.

Still another object of the invention is to provide a simplified feedingand pressingfattachment that is relatively cheap to manufacture,efficient in service, and neat and compact. "in form and arrangement.

With these and other objects in view, the invention consists in certainnew and novel features and combinations of parts, as will be hereinaftermore fully explained and pointed out in the claims.

It might be mentioned at the outset that I have illustrated only so muchof the sewing machine as thought necessary to illustrate the manner inwhich the attachment is applied and the relative positions of the partsof the attachment as associated with its cooperating parts of the sewingmachine.

Referring now for the moment to Fig. 1; there is shown a sewing machinehead consisting of the base I, standard 2, overhanging arm 3, and table4, while above this table may be seen a part of the attachment thatforms the subjectmatter of the present invention.

Sewing machine-feed mechanism Referring now for the moment to Fig. 2,and outlining briefly those parts of the sewing machine thoughtnecessary to enumerate to understand the present invention, there may beseen the main drive shaft with a fragmentary part of the oil reservoir Eto the rightof the gure,

while secured near the outer end (left of the i'lgure) is an arm 1,which is pivoted on a frame, which, in turn, is pivotally mounted on arock shaft 8 mounted in suitable bearings 9 and I0. The arm 1, shown indot and dash lines in Fig. 3, is rocked from the main drive shaft 5through the eccentric Il and its strap I2 connected to the arm l at thepoint I3. The arm 1 is also connected to the vertical frame or link I4,while at the top of this link is further pivoted the arm I5, whichextends forwardly of the machine to substantially beneath the presserrod I6. The outer end of the arm I5 is enlarged and provided with aguideway I1, in which is adjustably mounted the feeding dog I8, thelower portion of which is provided with the bifurcated short arm I9,which ts within the aforementioned guideway I'I, so that the feeding dogI8 may be slightly adjusted vertically and held in the desired positionby the clamping screw 20'.

Asv far as the specication has proceeded, it will be seen that arotation of the main drive shaft 5, through the aforementioned eccentricstrap I2, arm l, and arm I5, will impart a horizontal reciprocatorymotion to the feeding dog I8.

To impart the vertical reciprocatory motion to the feeding dog I8, adepending arm 2|, forming a part of the arm I5, is secured at its lowerend to theeccentric strap 22, which, in turn, cooperates with theeccentric 23 mounted on the main drive shaft 5. Thus, the properly timedhorizontal and vertical reciprocatory motions impart the desiredcompound motion to the feeding dog I8 to feed the cloth through themachine, with the assistance of the presser foot, in the conventionalmanner.

Looper To impart the desired movement to the looper mechanism, there isshown an auxiliary or rock shaft 24, which is suitably mounted inbearings 24', and from which shaft extends the curved arm 25 (seeFig. 3)to which, in turn, is secured the eccentric strap 25, which' cooperateswith the eccentric 27 also mounted on ythe main drive shaft 5, so thatthe rotation of the main drive shaft 5 also rocks or oscillates theaforementioned auxiliary or rock shaft 24. This rock shaft 24 has asleeve 28, which is held in position by the set-screws 29, which, inturn, carry the bearing 30, in which the stub shaft 3! is mounted, andon which shaft is pivotally mounted the arm 32, to the upper end ofwhich latter is adjustably secured the looper 33 that can be seen justadjacent the needle 34.

The mechanism just described provides the lateral or needle-avoidingmovement of the thread looper.

To provide the I reciprocatory motion to the thread looper, there isshown the link 35, which is adjustable by providing the internallythreaded barrels 3B and the right and left-hand threaded member 3T, sothat an adjusting movement of this right and left-hand threaded member3'I will cause a shortening or lengthening of the link 35, dependingupon the direction in which it is turned. This link is reciprocated fromthe shaft 5 by a cam (not shown) Due to the compound movement, that is,the needle-avoiding movement and the reciprocatory movement, thethreaded looper may pass and avoid the needle in properly timed relationwith the vertical reciprocatory movement of the needle 34.

Having thus briefly described one form of conventional machine withwhich the seam pressing attachment may be used, reference will now bemade to the attachment forming the subjectmatter of the invention.

Referring again for the moment to Fig. 2, there will be seen rigidlysecured to the main drive shaft a worm 33, which, in turn, drives thepinion 36, which is rigidly secured to the Vertically extending shaft40. This shaft is mounted in the housing 4l secured on the base I. Onthe upper portion of the shaft 46 may be seen the knurled roller 42,which may be removably fixed to the shaft 40 by the Allen hollow screwY43. The pinion 39 for driving the shaft 46 vwill also be locked by thehollow set-screw 44 and may be changed or replaced, ifv ever necessary.Y

Now the ratio of the worm and pinion for driving this knurled roller 42is commensurate with the rate of feeding movement of the feeding` dogmechanism, so that not only will this roller press the seams, as will beshortly described, but it will also give a slight pulling movement tothe fabric from the seaming operation. Thus, there is no possibility ofthe work being jammed between the needle and the feeding rolls, and bythus properly timing the roll with the feeding mechanism the fabric willbe advanced in proper time with the feeding and stitching operations.

It will be noticed in Fig. 2 that the arm l5 is cut away, as at I5', toclear the lower portion of the periphery of the knurled roller 42.

Referring now to that part of the attachment which is mounted above thetable, attention is drawn particularly to Figs. 3 and 5.

On the table 4, as may be seen in Fig. 5, there is mounted an L-shapedbracket 45 having the short leg 46 and the long leg 41, the short leg,in turn, having a pin 48 secured thereto, which is mounted in the tableand has secured to its lower portion the arm 49, which extends insubstantially the same direction as the short leg 46.

At the outer end of this arm 49 may be seen aY spring 5G, which issecured, as at 5I, to the under surface of the table. so that the longleg 41 is normally held inwardly under tension toward the roller 42.

It will be noticed that the leg 41 is the support or housing for acompanion roll 52 to the knurled roller 42. Directly in back of the roll52 may be seen the small dogr or guide 53, which is pivot-ally mounted,as at 54, and also held under tension by the spring 55. This dog 53, aswill be mentioned later, bears against the presser foot, about to bedescribed, and insures the proper feeding of the cloth to the driven andidle presser rolls 42 and 52 just mentioned.

In Figs. 3 and 6. it will be noticed that the table 4 is provided withwhat I term an auxiliary table or bridge 56, which extends upwardly fromthe normal plane of the table 4, and it is on the bridge 56 that thecloth is placed when being fed to the needle and rolls. f

This bridge may be in the form of a pressed or molded plate, having thefront wall 51, Fig. 3, while the flat upper surface has the twoelongated cut-out portions 58, in which the feeding dog I8 oscillatesand the central opening 59, Fig. 6, through which the needle operates.There is a rear wall 6B of the bridge that extends downwardly andoutwardly and is then secured to the under surface of the table 4, as atSi. Just in front of the bridge, as may be clearly seen in Fig. 3, thereis a small inclined member 62 to fav cilitate' thevfeeding of the clothand prevent it from striking the vertical wall 51.

In Fig. 6a, there is shown a detail section taken across the front ofthe bridge to show its contour, and Fig. 6b is a longitudinal sectionshowing the configuration of the bridge throughout its length.

It will be noticedin Fig. 6 that the top surface of the bridge slopesdownwardly, as at 63, from the side of the plate toward the rear thereofto permit the marginal edgeof the cloth, that is to be pressed back, todeflect downwardlyand be guided in this deflected, now vertical,position until it reaches the rolls. There will also be noticed thatformed on the bridge, that is, from front to rear, is the elevatedportion 64, which conforms inoutline tothe outline of the presser foot65.

It will be understood that the ordinary presser foot is removed from thepresser rod I6 and the present presser foot 65 substituted therefor.

The presser foot 65 is turned up at its forward end, as at 66, tofacilitate the entry of the cloth thereunder and is also provided with aneedle opening 61. The presser foot is rockably secured, as at 68, tothe short arm 69, which is, in turn, clamped to the lower end of thepresser rod I6. This rockable movement allows the presser foot to rockor to `adjust itself to firmly press the fabric against the feeding dog.

The rear end of the presser foot tapers to a point extending in adirection centrally between the two rolls 42 and 52 and conforms inshape to the raised portion 64 of the bridge plate, as shown in Fig. 6.

It will be noticed that the longer leg 41 of the bracket 45 is slightlyabove the, plane of the raised portion: 64 over which, it will beremembered, extends the presser foot (see Fig. 9) and the upper surfaceof the leg 41 slopes laterally downwardly toward the plane ofthe raisedportion 64. y

It might be mentioned here that the leg 41 also, near its outer end, isbifurcated, as at 41', to receive the heretofore mentioned roll 52, thedog 53, and spring 55.

Also mounted on the bridge is the irregularly shaped guide plate 1l,which has the straight edge 12 and the rounded outer edge 13, thestraight edge 12, however, deflecting inwardly, as at 14. This plate 1I,at its outer end, is pro'- vided with what might be termed a sh-tailportion extending at right angles to the upper surface of the plate toproperly guide the opened margins of cloth. On the under surface of theplate there may be seen a small spacing block 16, while at its forwardend there is a pin 11, which extends through the table 4 and has securedto its lower end a spring 18, which is fastened, as at 19, so that whenthe plate is in position, as shown in Fig. 5, the rear end with thefish-'tail portion abuts against the raised portion 64 of the bridge andagainstthe tapered end 10 of the presser foot, and it is the lower edgeof this fish-y tail that deflects the marginal edge of one of the piecesof fabric being stitched. The guide plate 'il is pivotally mounted atthe point 88 on the bridge.

By providing the small spacing blocks 16, the upper surface of the plate1l will extend in a, plane slightly above the upper surface of thepresser foot, so that when one layer of the cloth is passed under theguide plate 1l and the presser foot is lowered into its holdingposition, the marginal edge of the yother piece of `fabric lwill assumethe upright position, as shown in Fig. 9.

Having described the sewing machine in general and the structure of theattachment in particular, a brief description of the operation of theattachment follows.

Operation Referring for the moment to Fig. 9, there will be seen twopieces of fabric A and B, which are to be stitched, as at S, and whichare to have the marginal edges a and b turned back on the cloth andneatly pressed.

The pieces of cloth A and B will be positioned as shown in Fig. 9, thatis, the piece A will be laid on top of the L-shaped bracket 45 to passunder the presser foot 65 and then extend upwardly between the edge ofthe presser foot and the straight edge 'I2 of the plate 1l. The piece Bpasses under the L-shaped bracket, under the presser foot S5, andbeneath the plate 12, the spacing block 76 on the under side of theplate providing clearance for the cloth and limiting the amount of themarginal edge b to be turned back.

The presser bar having been elevated by a lever (not shown) will then belowered, so that the cloth, just before the stitching proceeds, will bein the position as shown in Fig. 9, that is, the marginal edge -a in asubstantially upright position and the marginal edge b in a horizontalposition.

The machine will then be started and the layers of cloth advanced untilengaged by the feeding dog. As the material advances, it will bestitched and the marginal edge a of the piece A will pass along thepresser foot until it reaches the tapered portion of the presser footand the fish-tail of the plate 1|, where it will still be guided in thisupright position until it has engaged or passed into the bight of therolls. The marginal edge b of the piece B, however, will pass along in ahorizontal `plane until it strikes the lower inclined edge of thefish-tail 15, as may be seen in Fig. l1, which deflects it in a downwarddirection, it being remembered that this is permitted by the cut-away orinclined portion of the bridge, as at 63. The upper inner surface of thefish-tail, as will be remembered, holds the marginal edge Iat inanupright position, Fig. 1l.

Thus, it will be seen that the fish-tail not only, by its inner surface,holds the upper marginal edge a, in an upright position, but it also, byits lower edge, deects the marginal edge b downwardly and, when sodeflected, also holds the marginal edge b in the same vertical plane asthe marginal edge a.

Therefore, when the cloth, with its stitching and its marginal edges,reaches the rolls, the one marginal edge is turned upwardly and theother turned downwardly and in a position to be pressed.

'Ihe tension on the spring 5B together with the relatively long armholds the idle roll 52 tightly against the cloth and against the largerdriven roll 42.

In Fig. 12, the fabric is shown as passing between the two rolls, andafter the material has been passed through the rolls and the two layersopened out, the now-pressed marginal edges a and b will lie neatly andflatly folded and pressed back on the cloth.

From the foregoing, it will be seen that I have provided an extremelysimple and eicient attachment that may be readily applied toconventional types of sewing machines that will neatly fold and pressthe marginal edges of the cloth adjacent the seam back on the cloth andthus do away with the later hand ironing.

Furthermore, I have provided an attachment wherein the main pressingroll is driven from the main shaft of the machine, and by using a properratio of worm and pinion, the pressing roll supplements the normalfeeding mechanism of the sewing machine.

Consequently, the machine may be run at a very high rate of speedwithout any danger of the fabric jamming between the needle and therolls. Furthermore, there are but few parts above the table, and theseparts in no way hinder the normal sewing operation.

Lastly,'when the machine is to be used otherwise than for pressing theseams, either one or both rolls may be removed with but littlediliculty.

Having thus described my invention, what I claim vas new and desire tosecure by Letters Patent is:-
